Su Wan, holding dual degrees in modern agronomy and emergency medicine, dies suddenly and crosses into a famine novel, becoming the vicious abandoned wife who at the very beginning abandons her young son and runs off with the family's last seed grain. In the original story, the moment she leaves, her husband works himself to death and her two children starve to death, leading to the destruction of the entire family. Bonding with the Vitality Shuttle System, relying not on heavenly divine power but solely on her family staying alive and the earth growing food, she can accumulate energy to briefly travel back and forth to the modern era. She must clear her name, protect her family, and in a barren disaster year step by step grow food from the desperate plight of chewing tree bark, guarding her home.
